From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Run sudo dmesg | grep amdgpu and look for errors.
You may have a firmware file missing, for instance. If that’s the case, it’s an easy fix - just download the firmware files from the kernel tree and put them wherever your system wants them.
This is how I do it on Debian but it should be easy enough to adapt to whatever distribution you’re using (it might be exactly the same tbh): https://blog.c10l.cc/09122023-debian-gaming#firmware
the most bug-free gpu experience I have with Linux is Nvidia GPU + KDE X11 with compositor disabled. Pure bliss. I've had a 6700XT and it was terrible too, now I have a 4070. For my laptops, intel igpu works decently well with wayland KDE, but there are few bugs, like having to clear some apps gpucache (vscode) quite often
At least with my 1060 compositing wasn't an issue. But true, I rarely used Wayland. Do you have specific issues when compositing is enabled or do you just prefer the simpler rendering?
I prefer without for the aesthetics but also for functionality: compositing x11 with multi monitors of different refresh rates is still broken, everything becomes locked at 60hz instead of the max for each monitor.
Using amd GX 6600... Mostly going fine, tho I haven't tried any big heavy games. One thing tho... Everytime I turn on my computer, no display. I reboot it and then ot works fine, but ot never does the first time. One path I'll investigate is the monitor: my monitors are both older and use DVI or VGA ports, so I have to use converters. I might try and get my hand on a more recent monitor to see if I still get the same problem. But if I do, I'm not even sure where to ask. I don't even think it's a linux problem, because I tried removing my drive with linux living one with windows and the problem remains. I also was using mint when the problem started and switched to Arch (btw) since and it doesn't change a thing.
I had a similar problem which was resolved by disabling the motherboard integrated graphics in bios settings.
Thank you ! It didn't seem to work on it's own, but I also noticed I wasn't booting in EFI mode, so maybe if I just change my booting partition and combine it with your advice it'll work...
Mine went back to no display only on boot, so I guess it didnt work for me either :( good luck tho!!
Aw, too bad :( Good luck to you as well, tho! I've bookmarked your comment, so I'll be back to tell you if I find the solution, however long it takes!
I still haven't found the solution, have you had any luck with yours?
I tried switching every UEFI setting that seemed to have something to do with booting or gpus, reinstalled gpu bios, upgrading mobo bios, getting a monitor I could plug without a switch... All to no avail.
Well, I think before upgrading the BIOS, one thing had a slightly different result: Setting the boot mode to UEFI and disabling CSM made it display "no gop (graphic output protocol)" after a few minutes, and it offered to either take me to the uefi settings or loading defaults (which implied going back to CSM), after which it boot this time go back to doing the same thing.
I don't think I've had this error since the mobo bios upgrade, but still no display unless I reboot, unless the computer had been turned in until recently. I'm kinda out of ideas...
…unfortunately no.. I work around it by knowing what buttons to press but it’s pretty stupid.
I don't know if you've tried it yet, but having recently installed 6.7.3 I noticed a whole lot of amdgpu fixes in the changelog. Maybe it will help?
Update: today I was able to update to kernel 6.7.5 and the issue disappeared for me.
If it makes you feel any better you're not the only one. I also have this problem. Whenever it was time to upgrade my video card I'd try Ati and later AMD and it would always have some annoying issues. Meanwhile I'm on my 7th or 8th Nvidia card over the years and they're always great.
